AUTOMATIC THREADING DEVICE FOR WINDING-MACHINES.

SPECIFICATION forming part of Letters PatentNo. 649,088, dated May 8, 1900.

. Application filed November 14, 1898. Serial No. 696,461. (No model.)

To all whom it may concern.-

Be it known that I, SIMON W. WARDWELL, J r., a citizen of the United States, residing in the city and county of Providence and State of Rhode Island, have invented certain new and useful Improvements in Automatic Thread ing Devices for Winding-Machines, of which the following is a specification.

In different classes-of machines in which there are thread carriers and tension devices difficulty has been experienced in connection with the operations from the fact that it is necessary to manually open and hold open the tension devices during the adjustments or insertion of the thread while passing it to the thread-carrier. This has been specially the case with some forms of thread-winding machines, and in such machines where reciprocatin g thread-guides are employed it has heretofore been necessary to place thread in the notch of the guide before the starting of the machine, as otherwise the thread would run onto the spindle inbelts or ridges instead of being evenly laid or would be thrown beyond the limits of the cop or package in a shapeless mass, ruining the package and wasting the material and the time of the attendants. To avoid these difficulties and secure other advantages, I have devised certain means, fully set forth hereinafter and illustrated in connection with a winding-machine in the accompanying drawings, in Which Figure 1 is a front elevation of part of a winding-machine embodying my improve ments. Fig. 2. is a side elevation. Fig. 3 is a plan View. Fig. 4 is a detached sectional plan on the line T, Fig. 2. Fig. 5 is a section on the line 5 5, Fig. 2, drawn upon an enlarged scale. Fig. 6 is a detached View of the thread-guide and part of the guide-carrier.

My invention is adapted for use in difierent classes of machines in which are combined thread-carriers and tension devices.

According to the character of the machine the thread carrier may be a threadguide, needle, or spindle or other part to which the thread passes after passing through the tension device, and the latter may be constructed in any suitable manner so as to provide two or more separable parts, between which the thread must pass. While I shall refer to these devices as a thread-carrier and thread-tension, it must be understood that the material operated upon maybe rope, thread, yarn,- wire, 8Z0. With such carrier and separable or two part tension I combine devices of any suitable character which will insure the opening of the tension device to receive the thread when the machine stops and close the said device to apply the proper tension to the thread when the machine is started. These variousparts will be differently constructed in different machines or different characters of machines; but I have in the drawings illustrated a construction with the thread-winding machine shown in my Letters Patent No. 567,871, dated September 15, 1896, and with separable thread-tensions substantially like that of my Letters Patent No. 57 7,337 dated February 16, 1897.

I have used in most instances the same lotters and figures of reference in connection with the machine illustrated in the drawings in this case as are employed in my aforesaid Letters Patent No. 567,871, and will therefore not describe in detail all the parts, but will refer to the main features thereof.

In the frame A turns a spindle 9 and shaft 26, and concentrically with the latter swings the guide-frame F, in which reciprocates the guide-carrier O,su pportin g the guide I. There is also a stopping device (not shown) connected with the shaft 21, which is adapted to be turned by the spring 18 in the direction indicated by the arrow in Fig. 2 to cause the said stopping device to operate to stop the machine.

Extending from the shaft 21 is an arm provided with a detent-shoulder 46, which, engaging a corresponding shoulder 43 on the detent-lever E, resists the rotative tendency of the spring 18, leaving the machine free to run until such time as the aforementioned device is caused to operate to stop the machine. Pivoted to E is a member which I please to term the end stop-bar 51, having at its lower end the thread bearing-bar 56 and at its upper end a cam-face adapted to engage the periphery of a disk 53 on the shaft 9.

When the machine is winding, the thread bearing-bar 56. bears against the portion of the thread Y which is between the tension device and the thread-carrier and under such tension as to hold down the thread-bearing bar 56, thereby restraining the cam end of the end stop-bar 51 from coming into contact with the rotating disk 53. When the thread breaks, the cam end of the stop-bar 51 being the heavier drops into contact with the disk 53, which, rotating in the direction of the arrow, carries it downward, pushing outward the lever E, releasing the shoulders 43 46 from contact, when the spring 18 willturn the shaft 21 and stop the machine. The parts are reset by means of a hand-lever E, by means of which the shaft 21 may be rocked back un til the shoulders are engaged, the lever E being thrown upward by a spring 31.

The tension device, as shown,cons1sts of stationary comb or series of fingers c and a similar comb or series of fingers f, which is pivoted on a vertical rod 6. The fingers in l these two series or combs are so disposed that i in order to open the tension for threading the movable comb f is rocked on the rod 6 in the direction indicated by the arrow inFig. 4 un-; til its fingers, passing between those of the fixed series on comb c, assume the position indicated in Fig. 4, as well as by the dotted 30.

The thread Y is passed movable series f close upon it and by forcing it between the fingers of the fixed comb andcausing it to travel in a more or less devi-. ous path imparts an amount of tension dependent upon the force applied to the mov- As shown in the drawings, in this case a yoke a is pivoted to the movable fingers at its ends and is connected 1 by a small cord b, passing through an eye Y,

As shown, an arm P, having an inclined slot 99, is secured to I the shaft 21, and the slot 19 receives the bent end of a rod 0, pivoted to the cam end of the 43-4E6are released and the slotted end of the arm P rises the lower end of the end stoparrow, Fig. 2.

device, which are thus held open,so as to readily permit the thread to be drawn between the two sets of fingers or to allow another thread to be inserted.

Then the lever E is turned to start the machine, the arm 1) is also moved, thereby allowing'the rod 0 to take any position to which the end stop-bar 51 may drag it as the heavy or cam end thereof falls. This latter motion causes the opposite end of 51, which carries the thread bearing-bar 56, to rise, thus relieving the pressure on the lever Q and permitting the tension to close.

In order to avoid delays incident to adj usting the thread in the tension device, I provide the latter with suitable thread-guiding devices-as, for instance, with guide-wires 11. m, converging toward the point where the thread is to remain and allow its ready insertion, when the draft upon the thread will carry it to its position to be caught between the two parts of the tension device, whence it will be carried over the thread bearing-bar ,ftlld. attaches it to the spindle for winding.

To obviate the necessity of placing the thread in the notch of the traversing thread-guideI and to avoid the waste and damage already pointed out, due to the thread being pushed over the end of the cop, I use a traversing guide of special structure. This guideI has its top so formed that it will pass under the thread until the latter reaches the notch provided for the purpose, into which it falls.

In order to support the thread so that it shall be readilyand properly picked up by the traversing guide, I provide a longitudinal thread-supportin g bar 5, adjacent to the traversing thread-guide I and parallel to the path of traverse of said guide.

The traversing thread-guidel will usually pickup the yarn without difficulty at any point on the bar 5; but it sometimes occurs when the yarn is dropped near the extremity of the bar that the edge of the guide tends to push the yarn over the end of the cop before the guide can pick the yarn up. In the construction shown the yarn remains on the bar 5, and the upturn at the end of the bar raises the yarn, so that the edge of the guide can push the yarn no farther; but its elevated position allows the guide to slide under it, when it will draw into the slot in the guide.

The guide I is shown as separable from the carrier 0. To secure a ready attachment and detachment of the guide, I provide the latter at the bottom with a spring-fork s and with an intermediate socket u to receive a stud 0' upon the carrier 0, having inclined edges so arranged as to bear upon the sides of the lower stud r and tend to draw down the guide,

so that when the latter is applied to the studs it will be held firmly under tension without any tendency to become loose and rattle and yet capable of being readily withdrawn by the application of a comparatively-slight upward pressure.

In order to avoid the necessity of machining the end stop-bars 51 to make them of uniform length, I make the thread bearing-bar 56 adjustable upon the bar 51. This may be done in different ways. As shown in Figs. 2, 3, and 5, the bar 56 is offset, with a threaded stud or projection at one end extending into a transverse threaded opening in the bar 51, so that by turning the bar 56 to different positions it may be set as required. As a means of securing the bar 56 in its position I thread the end of the bar 56 and pass it in the opposite direction into the same opening in the bar 51 until it bears against the end of the stud of the bar 56.

By the means above described I am enabled to properly place the thread in the tension device and secure its proper insertion in the eye of the guide without the necessity of any attention to these details upon the part of the operator. Further, the tension device is opened to permit the ready movement of the thread or the insertion of another portion of the same thread or another thread whenever the machine is brought to rest and is automatically closed when the machine is started.
